Selected matches will be held over to the venue in Milton Keynes, while the other first round matches will take place in the qualifying round in Wigan from August 9 to 14. The format will be released soon.

First draw only,  because a random draw is made ahead of each round for this tournament.

The sentence about Ronnie and Alex Ursenbacher puzzles me a bit. Yes, Alex beat Ronnie in that match, but Ronnie has since beaten Alex too, and Alex had beaten him before in the 2019 Welsh Open. Why that match in particular? Especially as the previously annouced format for this comp is best of 7 in early rounds like in the Home Nations events. Anyway…

I have put some matches in bold… those I feel might be close and interesting!
